Kosst, Here are just a few examples of amps that had large power supplies that I have owned, with never a blown fuse. Ampzilla, Krell KSA 50 and Mk 2, Bedini / Strellioff 200, Bedini 25 / 25, Robertson 6010, Threshold 400, Threshold Stasis 2, Audionics CC2, ARC D 50, 60, 100, Crown Studio Reference, SAE 2600, so many Mac’s, and the list continues. So stop your BS.
